BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates generally to ice skates in particular to an iceskate including the arrangement of elements to provide a shock absorbentsuspension mechanism to enable the ice skate to be used on irregularriding surfaces and for acrobatic type of riding mode including but notlimited to jumping and the like by an ice skating passenger.

2. Background

A common ice skate comprises a top platform with the sole of a bootsecured to it for the foot of ice skater. Under side of top platform ishaving support brackets affixed along longitudinal centerline thereofhaving a skating blade rigidly connected vertical plane. The skates ofthe type as aforesaid are well known in the field of ice skates andexist in many configurations and sizes. The type of suspension forskating blade does not include an elastic element for shock absorbencyto cushion leg of skater during skating action especially when jumping.A great number of ice skaters are motivated to perform long jumping orother like features which requires a great deal of physical effort bythe ice skater to get airborne per se and consequentially requiringappropriate leg action to provide for a cushioned landing to preventinjury to the bracing feet and legs. The rigid type suspension ofskating blade requires a considerable skill of the ice skater to performacrobatics type of ice skating and then at best with a great effort ofpractice and physical effort.

3. Description of Related Art

U.S. Pat. No. 5,931,480 describes a foot gear suspension device withmovable swing arm at front end with a nonrotating axis mounted to distalends of said swing arm having free rotating follower bearing guided inan elongated hole of skating blade along the horizontal plane. Oppositeend of said swing arm is pivotally attached to frame work of said footgear having a secondary pivot pin in line with said pivotal attachmentconnecting to a linear elastic element such as an air, hydraulic, orspring cushioned piston or the like. The length of distance between saidpivot pins determines the degree of leverage and such articulatedmovement in the vertical plane of said swing arm. Rear end of saidsuspension device is having another swing arm suspended from frameworkin an identical arrangement. Said swing distal end is pivotally attachedto skating blade. During skating the weight of skater applied to saidfoot board in combination with skating action the like of pushing theskate against the skating surface effects said swing arm to deflect downwardly in an articulated movement and upon recoil of elastic elementassist the ice skater towards enhanced acceleration in forward motion.Arrangement of said swing arm may afford a shock absorbency to leg ofskater during skating activity especially when running againstprotrusions in surface or during maneuvering around other likeobstacles. The type of fixation of said swing arm provides sufficientclearance to said framework of said footgear during articulated movementof said swing arm. Hence forth it appears this invention teachesoptimization of movement in vertical plane of said swing arm having saidskating blade therefore providing sufficient capability for skater toperform jumping, negotiating obstacles and the like. Said inventionamong others does not teach how the elasticity of said swing arm istranslating a proportional equal or nearly equal force of reboundthrough out the complete range of pivotal and articulated travel of saidswing arm. Specifically this invention does not explain sufficiently therelationship of the type of elastic element the like of air, hydraulic,spring and other referenced herein and how these elements are connectedto and interfacing with said primary and said secondary pivotalarrangement of said swing arm. The present arrangement as shown and asspecified in this invention may not make provisions for optimizedutilization of vertical movement of said swing arm and may distribute adisproportional force of rebound in relation to the position of saidswing arm and along total travel range thereof. In retrospect theskating may be very limited resulting in diminished effectiveness forjumping, acrobatics, negotiation of obstacles, surface irregularitiesand the like. Aforesaid is manifested by a progressive change inelasticity or rebound force therefore requiring for the ice skater tocompensate with proper leg action, balancing and physical strength.Therefore it may be highly likely that a diminished rebound force isassisting the ice skater wherein greater force may be required and inretrospect a greater force may be delivered when a smaller force forrebound may be sufficient. Limitations in the ability of ice skater touse rebound assist for acceleration in forward motion and performingjumping, acrobatics or negotiating skating surface obstacles or the likemay greatly increase the need of ice skaters skill level and physicalstrength and may render a marginal skating stability at best. Saidinvention also fails to teach proper fixation of said swing armarrangement along the horizontal center axis of said pivot arrangement.Because of distal length from said pivot arrangement to said pivotalarrangement and follower respectively of said swing arm lateral forcesor thrust applied to said swing arm by ice skater are of considerableforce requiring a positive fixation to said swing arm along longitudinalcenter axis of skating blade and frame work respectively the like ofwear plates straddling said swing arm in contiguous mode ratherdepending solely on said swing arm pivotal arrangement. Aforesaid maycontribute to a greatly diminished ice skating stability and safetywhich more so with ice skaters is of significant importance to the iceskaters safety when negotiating sharp turns, steeply banked cornerriding, quick stops and the like. It is of great attraction to an iceskater and of great incentive to acquire the skills of ice skating andonce acquired to perform acrobatic type ice-skating. Therefore an iceskater applies on a very frequent basis significant thrust onto saidfoot gear suspension requiring a considerably contained ice skatingblade suspension delivering superior r grasp of ice skating blade uponthe skating surface. The like arrangement of said swing arm of thisinvention in combination with the distal length between pivot axle andfollower bearing axle respectively and pivot point of said swing armexcluding a means of proper containment of said swing arm along thehorizontal axis the like of wear plate and other fixation elements maynot contribute to a desired skating stability for the ice skater and maylimit significantly skating flexibility and safety. For furtherconsideration this invention fails to teach that said ice skating bladeremains stationary along longitudinal axis. Said pivotal arrangementconnecting rear portion of said skating blade with distal end of saidswing arm will move skating blade in reciprocating fashion along thelongitudinal axis during articulation of said swing arm. This may proveto be very undesirable to the ice skaters ability to negotiate jumps andsave landings after completion of said jumps in a save and calculatedmanner. Afore said is of considerate consequence to the safety andskating ability for a skater due to the fact that that the forcedlongitudinal travel of said skating blade is caused by said pivotalsuspension of said swing arm to rear portion of ice skating blade andtherefore may not provide the ice skater a permanent reference point ofsaid skating blade when performing jumps and other like acrobatic iceskating. Furthermore said invention does not teach having said skatingblade contained and arrested laterally along the horizontal axis. It isof great importance to a ice skater that said skating blade must nottilt along the vertical plane and be fully contained along thehorizontal plane. Aforesaid is even of greater significance when iceskating is performed including jumping and acrobatics due to the factthat a save and sound landing is solely guaranteed only if said skatingblade is rigidly connected to said chassis of said foot gear. Any slightmovement, wobble or other instability of said skating blade duringmaneuvers the like of acrobatics, sharp cornering, and jumping mayresult in falls of the ice skater and may cause injuries not to mentionadditional disadvantages the like of poor skating control and diminishedskating performance.

My prior art search with abstracts described above teaches: several footgear suspensions including a design, but fail to teach an in line skatewith a fixated and unrestricted and shock absorbent skating wheelsuspension describing an articulated movement to be of constantdeflection force through the complete range of articulated movementwithout restrictive features to limit articulated movement. The presentinvention fulfills these needs and provides further related advantagesas described in the following summary.

Construction of an ice skate must demonstrate that skating blade ispositioned as such to provide precise alignment along longitudinalcenter axis in relation to skate frame. Aforesaid feature is of greatimportance to the skating stability and safety of an ice skater.Aforesaid is achieved and very common with many ice skates commerciallyreadily available. Afore said may not be readily demonstrated with anice skate having an articulated and elastic skating blade suspension. Anembodiment of this invention is demonstrating that an ice skate havingan articulated and elastic skating blade suspension is providing skatingstability and safety equivalent to present available ice skates withoutan elastic skating blade suspension in addition to having all theadvantages of an ice skate with elastic wheel suspension. FIG. 2 showsthe bottom plan view of an embodiment of this invention. Specialdesigned skating boot 48—not shown—is firmly affixed to boot supportplate 32. Platform 30 in horizontal plane is having plurality of sidebracket 15 affixed with plurality of counter sink screw 17 as referredto in FIG. 6. Plurality of extension arm 12A and 12B respectively ispivotally and coaxially affixed on plurality of axle 16 with extensionarm 12A opposing extension arm 12B in mirror image. Plurality ofextension arm 12A and 12B respectively is having axle 20 non-rotatingaffixed to distal end thereof with plurality of lock washer 44 andplurality of nut 34 threaded onto end of plurality of axle 20. Pluralityof axle 16 is protruding plurality of side bracket 15 having pluralityof lock washer 44 and nut 34 threaded onto end thereof. Plurality ofside bracket 15 is straddling plurality of extension arm 12A and 12Brespectively with plurality of wear spacer ring 28 placed on pluralityof axle 16 in rotating fashion with plurality of wear spacer ring 23 asreferred to in FIG. 3. Plurality of wear spacer ring 28 is contiguouswith face of plurality of side bracket 15 with opposite side thereofcontiguous with face of plurality of spacer 46 as referred to on FIG. 3.Plurality of wear spacer ring 23 is contiguous with face of plurality ofhub of extension arm 12A and 12B respectively. Plurality of extenderbracket 33 is centrally affixed to plurality of side bracket 15 opposingeach other in coaxial and mirror image fashion having axle 20 nonrotating affixed protruding thereof with plurality of lock washer 44 andnut 34 threaded on opposite ends of axle 20. Plurality of wear spacer 31is affixed to opposing face of plurality of extension arm 12A and 12Brespectively and contiguous with vertical face of skating blade 10.Plurality of wear spacer 35 is affixed to opposing face of plurality ofextender bracket 33 and contiguous with skating blade 10. Plurality offollower 24 is non rotational affixed to plurality of axle 20 engagingin free rotational fashion with plurality of horizontal elongated hole24A and vertical elongated hole 24B respectively as referred to in FIG.6. As is shown on FIG. 6 plurality of wear spacer 31 and plurality ofwear spacer 35 respectively is affixed to plurality of extension arm 12Aand 12B respectively with plurality of counter sink screw 39 andplurality of counter sink screw 37 respectively. It is note worthy tomention that aforesaid is demonstrating the effectiveness of saidarrangement highlighting the confinement for plurality of extension arm12A and 12B respectively along horizontal center axis in a pivotalfashion. Additionally it is easily recognizable that precise alignmentfor skating blade 24 along the longitudinal axis is contained as suchthat misalignment and random dislocation thereof during skating actionis not possible.

FIG. 3 shows an embodiment of this invention in cross sectional view.Special designed skating boot 48—not shown—is firmly affixed to bootsupport plate 32. Platform 30 in horizontal plane is having plurality ofside bracket 15 affixed with plurality of counter sink screw 17—notshown—along underside thereof in vertical plane. Extension arm 12A and12B respectively is pivotally and coaxially opposing each other inmirror image affixed on plurality of axle 16 thereof is protrudingthrough hole for plurality of side bracket 15 at one end and oppositeend thereof with lock washer 44 and nut 34 rendering axle 16 affixed ina non rotating fashion. Plurality of side bracket 15 is straddlingextension arm 12A and 12B respectively with plurality of wear spacerring 28 placed on axle 16. Plurality of wear spacer ring 28 iscontiguous and slidably with face of plurality of side bracket 15 withopposite side thereof contiguous with face of plurality of spacer 46.Plurality of wear spacer ring 23 is contiguous with face of plurality ofhub of extension arm 12A and 12B respectively. Aforesaid isdemonstrating the effectiveness of said arrangement highlighting theprecise confinement of extension arm 12A and 12B respectively alonghorizontal center axis and axle 16 respectively. Aforesaid is highlighted due to the fact that the overall length of center portion ofaxle 16 is having a larger circumference than end portions thereof andto be of minutely greater linear length therefore exceeding the sum ofcross sectional length for plurality of wear spacer ring 28 and wearspacer ring 23 and plurality of spacer 46 and extension arm 12A and 12Brespectively. Therefore extension arm 12A and 12B respectively iscontained along the horizontal axis of axle 16 and capable of rotationalmovement thereof during use of this invention. Specifically containmentof extension arm 12A and 12B respectively is secured by the contiguouseffect with face of plurality of wear spacer ring 28 with plurality ofcontiguous face of side bracket 15 and the opposite side with pluralityof contiguous face of spacer 46 and respectively the opposite contiguousface of plurality of spacer 46 with the contiguous face of extension arm12A and 12B respectively with opposite contiguous face thereof andcontiguous face of wear spacer ring 23. Plurality of sleeve bearing 25is of free rotational fashion on axle 16 and is sweat fitted withextension arm 12A and 12B respectively rendering bearing sleeve 25confined to non rotational fixation.

Aforesaid is demonstrating the advantages of this invention over othershighlighting precise alignment of skating blade 10 along thelongitudinal center axis thereof additionally providing an effectivemeans to prevent any misalignment thereof during use of this inventionby an ice skater the like of sharp cornering quick stops and acrobatics.It is noteworthy to mention the importance of the precise confinement ofextension arm 12A and 12B respectively by simultaneously providingproper rotational bearing support thereof on axle 16. Plurality oftorsion spring 14 is encircled by counter bore of extension arm 12A and12B respectively and is aligned with plurality of spacer 46. Torsionspring 14 is of a wire material of a given hardness, elasticity, crosssection as well is having a certain number of coils therefore providinga certain spring force to be adequate for the desired torque strengthrequired and to be transmitted to skating blade 10 via partial rotationof extension arm 12A and 12B respectively. Plurality of torsion spring14 has an extension 52 along the horizontal plane at extremity of coilwith the like at the opposite extremity of coil thereof respectively.Plurality of extension 52 engages with plurality of through hole 50 andplurality of through hole 62 respectively therefore confining extensionarm 12A and 12B respectively to a given position or home position alongthe vertical plane depending on location of through hole 62. It iscontemplated that through hole 50 is of elongated configuration alongthe vertical center axis thereof. Aforesaid is to compensate fordiametrical change of torsion spring 14 during deflection thereof. Foran alternate method to compensate for diametrical change of torsionspring 14 an elongated hole 50 may be substituted with a dog pointurging against end portion of coil for torsion spring 14—not shown. Asalso referenced in FIG. 6 plurality of extension arm 12A and 12Brespectively is having plurality of through hole 62 to enable torsionspring 14 to be installed as described therefore locking plurality ofextension arm 12A and 12B respectively in home position.

FIG. 4 shows an embodiment of this invention in cross sectional view.Special designed skating boot 48—not shown—is firmly affixed to bootsupport plate 32. Platform 30 in horizontal plane is having plurality ofside bracket 15 affixed along underside in vertical plane lining up withedge of platform 30. Follower 24 is sweat seated on axle 20 contiguouswith plurality of sleeve bearing 25 engaging with vertically elongatedhole 24B in skating blade 10 in free rotational fashion. Follower 24 isa cam follower roller bearing readily available in many differentconfigurations. Axle 20 is protruding through hole for plurality ofextender bracket 33 with plurality of lock washer 44 and nut 34 threadedon either end thereof. Plurality of sleeve bearing 25 is rotationally onaxle 20 and non-rotationally affixed to plurality of extender bracket 33protruding clearance through hole for plurality of wear spacer 35 andcontiguous with follower 24. It is note worthy to mention that verticalalignment and containment of skating blade 10 along horizontal plane isa function of plurality wear spacer 35 straddling skating blade 10 in acontiguous and slidably fashion. Specifically urging upon vertical faceof skating blade 10 applied by opposing vertical face of plurality ofwear spacer 35 must be predetermined not to cause a friction betweencontiguous surfaces such impairing lateral movement of skating blade 10in vertical plane during use of the invention and not weak enough tocause wobbling and angular misalignment of skating blade 10. Aforesaidmay be easily accomplished by predetermination of cross sectional widthof plurality of extender bracket 33 and plurality of wear spacer 35 inrelation to length of follower 24 and length of plurality for bearingsleeve 25 which when combined must be slightly larger than the length ofsum of cross section respectively. An alternate method may be withpre-fabricated shim of varying thickness that easily can be installedsuch as sandwiched between plurality of extender bracket 33 andplurality of wear spacer 35.

FIG. 5 shows an embodiment of this invention in cross sectional viewwith cut-away. Follower 24 is sweat seated on axle 20 contiguous withplurality of sleeve bearing 25 engaging in free rotational fashion withhorizontally elongated hole 24A in skating blade 10. Follower 24 is acam follower roller bearing readily available in many differentconfigurations. Axle 20 is protruding through hole for plurality ofdistal end of extension arm 12A and 12B respectively with plurality oflock washer 44 and nut 34 threaded on either end of axle 20. Pluralityof sleeve bearing 25 is rotationally on axle 20 and non rotationallyaffixed to distal end of extension arm 12A and 12B respectivelyprotruding clearance through hole of plurality of wear spacer 31 andcontiguous and non slidably with follower 24. It is note worthy tomention that vertical alignment and containment of skating blade 10along horizontal plane is a function of plurality of wear spacer 31straddling skating blade 10 in a contiguous and slidably fashion.Specifically urging upon vertical face of skating blade 10 applied byopposing vertical face of plurality of wear spacer 31 must bepredetermined and not great enough to cause a friction betweencontiguous and slidably surfaces such impairing lateral movement ofskating blade 10 in vertical plane during use of the invention and notweak enough to cause wobbling and angular misalignment of skating blade10. Aforesaid may be easily accomplished by predetermination of crosssectional width of plurality of distal end of extension arm 12A and 12Brespectively and plurality of wear spacer 31 in relation to length offollower 24 and length of plurality for bearing sleeve 25 which whencombined must be slightly larger than the length of sum of cross sectionaforesaid. An alternate method may be with pre-fabricated shim ofvarying thickness that easily can be installed such as sandwichedbetween extension arm 12A and 12B respectively and wear spacer 31, notshown.
